2013-9-26 11:34:16

Floating pontoon type internal floating roofs is consist of a series of interconnected hollow tubular pontoons surfaced with a grid of beams and sheets. The annular space between tank shells is to be sealed by the primary foam seal & secondary wiper seal. Those seals can effectively reduce VOC emissions and project losses of the stored liquid products.

The pontoon type Internal Floating Roof is to be of the non-contact type per API650 Appendix H Section H Section H.2.2.e. 

CPEPT put the decades of experience in the design, manufacture, supply and installation of internal floating roofs to offer high quality and efficiency as well as eco-friendly products for all you need.

Our pontoon type internal floating roofs have three kinds of structure:  

  •      Bionic Grid Structure (Aluminum/Stainless Steel)
  •      Orthogonal Structure (Aluminum/ Stainless Steel)
  •      Hexagon Structure (Aluminum)
